Embolus

Endarterectomy

Hemodialysis

A process in which blood is shunted out of the body ad passed through a complex of set of filters for treatment of end stage renal disease---sometimes poisoning --- also called renal replacement therapy.

Venous stasis

Vessel loop

A device used to retract a vessel during surgery. A length of thin Silastic tubing or cottom tape --- umbilical ape -- is passed around the vessel. The ends can be threaded through a bolster 1/8 to 1/4 inch or 0.3 to 0.6 cm length of rubber Silastic tubing - - - - to secure the loop against the blood vessel.

Veins that dilate abnormally is called

Systemic circulation

Oxygenated blood in the LEFT VENTRICLE is pumped through the ascending aorta to the rest of the body. Blood returning from the body passes from the capillaries into the venous system and returns to the LEFT ATRIUM through the vena cava.

Pulmonary circulation

Deoxygenated blood in the right ventricle is pumped through the pulmonary arteries -- THE ONLY ARTERIES THAT CARRY DEOXYGENATED BLOOD --- to the lungs. Blood is oxygenated in the capillaries of the alveoli -- lungs --- and returns to the left ventricle through the pulmonary veins -- THE ONLY VEINS THAT CARRY OXYGENATED BLOOD.

Blood viscosity is measured by

The aorta

is the largest artery. Starts at the left ventricle. Descends through thoracic cavity. Passes behind the heart but in front of the spinal column. Enters abdomen passes through diaphragm behind the retroperitoneum space. Aorta bifurcates in the pelvic. Turns into the iliac arteries.

Thoracic cavity

Thoracic cavity. Starts from the left ventricle to form an arch - the aortic arch. Three major arteries come from this arch - - brachiocephalic artery, left common carotid artery, left subclavian artery. Still called the descending aorta at this point. Only when it crosses into the abdomen is called an abdominal aorta.

Veins carry blood

The largest vein of

The greater saphenous vein

The greater saphenous vein is used for arterial bypass

surgery. The greater saphenous vie is readily accessible, and its connective tissue layer thickens with increased pressure. This makes it strong and able to withstand higher arterial pressure and has adequate length.
